Beyonce Knowles and Jay-Z took their seven-week-old daughter to lunch at Sant Ambroeus in New York's West Village. The "Single Ladies (Put a Ring On It)" singer, 30, held her newborn close in a baby blue BabyBjorn.

On Monday, the hip-hop power couple attended the New Jersey Nets vs. New York Knicks basketball game at Madison Square Garden. Knowles has made few public appearances since giving birth January 7, save for her husband's special Carnegie Hall performance on Feb. 6.

Knowles and her husband (real name: Shawn Carter) even skipped the 54th Annual Grammy Award for an intimate pizza date at Lucali in Brooklyn, New York. "They were just like a regular couple," a witness told Us Weekly. ""hey were sitting in front of the place closer to where they make the pizza."

The fellow diner even congratulated Jay-Z, 42, on becoming a father. "He said, 'Thank you,' shook our hands, and said 'Have a good night.'"

Since becoming parents, Knowles has been holed up in the couple's Scarsdale, New York mansion and $6.85 million Tribeca loft nursing her daughter. "She has been totally doting on Blue," a source close to Knowles told Us. "She's up whenever the baby's up!"
